This is not good news for many users who will be forced to downgrade to SP2
http://news.zdnet.com/2100-3513_22-6123975.htmlMicrosoft will end support for Windows XP Service Pack 1 and SP1a on Tuesday, leaving people no option but to upgrade to Service Pack 2 if they wish to continue to receive crucial components, including security software.
The move to drop support for SP1 is in line with Microsoft's stated strategy for support. According to its guidelines, Microsoft guarantees to provide "mainstream support" for a full product for five years, but will only guarantee to support a service pack for 12 months after the launch of the next version of that pack.
SP1 shipped in September 2002. SP2 was released in September 2004.
There's little reason for anyone to still be running SP1; SP2 contained a range of improvements to XP's security. People can check which version they are running by right-clicking on the My Computer desktop icon and then selecting properties.
The ending of support for SP1 will help Microsoft to clear the decks for the arrival of Vista, which is expected to be released to business customers next month and to consumers in January.
In July, Microsoft ended support for Windows 98 and ME.
One of the hazzards of "updating" is the inclusion of newer .NET framework updates that destroy support for older but popular programs, instead it will claim the files are "damaged or corrupt", of course the files will work fine on a SP1 machine, looks like a forced lock-in to me.
As usual the policy is damage the older operating sytems to get folks purchasing the crap thats being offered called Vista, I,m sure many folks will not bother damaging their systems to obtain minor updates that seem to make no impact on the majority of usage habits.
